Obdurodon

Obdurodon (order Monotremata, family Ornithorhynchidae) A genus of early Miocene platypus, with two species, known from very well-preserved material from such sites as Riversleigh, Queensland, Australia. They possessed well-developed, functional teeth, unlike the living platypus, and had skull bones that were less fused, from which it can be seen that monotremes (Monotremata), unlike other living mammals, retained septomaxillae.

Notes:

Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.

In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
